Sophos Updates changing UAC and ACL in Windows?

A customer of ours has about 300 endpoints. 50 of these have some very specific UAC and ACL configurations in Windows. When we initally rolled out Sophos, these settings were reversed even though we have GPO setting this stuff up. Well, GPO never set it back up and we had to manually resolve. After this recent update, 10.8.1, it seems to have reverted again!

Has anyone else encountered things like this before? Our customer is ready to say Uninstall Sophos. These are critical machines that Sophos is breaking. I need to come up with another solution instead of Uninstall.

I have opened a ticket but have yet to even receive the automated email confirmation. May have to open it again.

Hello Keith Morris,

first of all, which product (SESC, Central, ...)?
Off the top of my head - certain Windows Security Options are reset during remediation (cleanup in response to a detection). I'm not aware that updating would modify global settings, but certain product related settings are set to their intended values. Actually install or update fails if settings aren't as expected (e.g. permissions on HKLM\Software).
Can you disclose which settings these are?

Sadly, I would consider this software Legacy as the UAC breaks this software. Additionally, the users have to run this software as Admin with special command line parameters. the Windows ACL that I mentioned is due to the user also needing write access to a few folders inside of Program Files.

Horrible programming on their part, I know. But our customer is quite invested in this software and not using it is not an option. We would have to ditch Sophos before they ditched this software.

I am going to look into the Application Compatibility Toolkit to see what it can do for us... But I am fearing we will have to remove Sophos on these PCs, at least until a fix is found...

Why don't you apply the registry value that is listed here ?

It is the fix that you are looking for.

Hello Keith Morris,

the user also needing write access to a few folders inside of Program Files
don't have (convenient) access to a Windows endpoint right now but I'll check. Off the top of my head I couldn't say which rights this would be.

the users have to run this software as Admin with special command line parameters
You've lost me here. Interaction with this software is, if at all, via the GUI. But maybe I miss which part you are referring to.

There seems to be some misunderstanding (it could as well be on my part).
